Those responses are 100% what I would expect them to say and they seem to boil down to what GRRM said years ago, bittersweet. They're all saying the same thing, some will love it, some will hate it, people won't be satisfied, people will be etc. Seems to me like it's going to be exactly what thrones has been, amazing but painful, and very controversial and bittersweet.
Again, not sure what you're expecting or wanting them to say, but those seem very much like the things I'd expect them to say. And it's amazing as well because it shows confidence that regardless of how upsetting the outcome might be, it has to be that way. It won't be Yub Nub or Dany and Jon flying off into the sunset with their newborn or something corny like that lol.
